Chemical Structure
Description
CATO supplies N-(1-oxo-5z,8z,11z,14z-eicosatetraenyl)-l-alanine (CAS 401941-73-9), a certified reference material (molecular formula C23H37NO3, MW 375.54 g/mol) for analytical method development and quality control.
N-(1-oxo-5z,8z,11z,14z-eicosatetraenyl)-l-alanine (C23H37NO3) contains a steroid core, an amide group, a hydroxyl group, an ether linkage. Its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), N-(1-oxo-5z,8z,11z,14z-eicosatetraenyl)-l-alanine meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
